alright i need some more help because you guys always seem to bail me out when im stumped my 4 banger just recently started bogging on me bad first it only did it when it was cold but now it last liek the first 5 minutes i drive it jsut randomly boggs down on me alkmost liek its gunna stall and i think its the tps again i went wheeling and sunk it pretty bad last weekend and its been doing it ever since i got the check engine light on its shooting the same codes it does every time the O2 sensor and TPS but they were both just replaced but the light went on again so i had my mechanic throw in another TPS thinking i jsut got a faulty one but its doing it again shooting both o2 and tps but they say the o2 is fine but the tps keeps going now i have two questions
is the tps the reson for this bogging because the other two previous times the tps went there was no symptoms the check engine light just went on so i changed it
or could the bogging be coming from something different
im going to throw some injector cleaner in it today but i alkready replaced the air filter im going to do all fluids plugs wires and disto cap today just cause its about do for all that and see if it runs any better and let you know but any input would be gratly accepted and thanks in advance
im having a similar problem that no mechanic has yet to solve. mine will bog down then back fire through the intake. if i change the tps you think my p[roblem will be solved on my 95 2.5? I have already changed all the iginition stuff and o2 sensor to no avail. I really just want my jeep to run right again somebody help us.
i've heard of ECM's going out/acting funny....never experienced it though. with some symptoms described it sounds like possibly fuel pump issues or pressure regulator..?? maybe fuel filter?? maybe put a pressure tester on the fuel rail and check it, i forgot what spec is...i'll look it up and let you know. it also could be timing, but if it runs fine for a while, then acts up, thats pretty much ruled out.
ive changed plugs and wires and all that jazz. havent checked the injectors they were next.maybe try the battery connections what did you do to fix that? I hope it doesnt have anyhting to do with puel pump filter or vaporized gas because i dont have the knowledge to change those yet but im getting there with every little part i change on this thing
i got a 6cly 4.0 liter and im havin this same problem. changed the fuel filter and the fuel pump and it still boggs down. check engine lighte comes on and everything. idk what it is but if someone can help ill be thankfull
battery lines are easy, just take a knife and go around the cable just enough to get fresh wire out and stick that into the terminal... you might as well clean them also, and check your grounds too. just get in there with a wire brush and go to town hahah
